to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a perspective view of one form which an endless woven belt embodying my invention, may assume.

Fig. 5. a perspective view of one of the modified forms which my improved belt may assume.

My invention relates to an improvement in spliced endless woven belts and methods of producing the same, the object being to produce a spliced endless woven belt which shall be smooth on both sides at the splice and supple and of full strength at such point at which the belt is not appreciably thickened.

With these ends in view, my invention consists in a woven fabric endless belt spliced by having the unraveled ends of its warp-threads passed transversely through the body of the belt-strip.

My invention further consists in amethod of producing woven fabric endless belts consisting in winding a belt-strip upon itself to produce a plurality of convolutio'ns oi belt-layers, then passing the unraveled ends of its warp-threads transversely through the body of the strip.

My invention further consists in further details and steps as will be hereinafter described and pointed out in the claims.

In carrying out my invention as shown duce an outer belt-layer 2 and an inner heltlayer3. The extreme ends of the strip are unraveled as shown in Fig, 3, by the removal of enough of the filling threads l to leave the ends 5 of the warp-threads (3 exposed and free. These exposed ends 5 of the warp-threads say from one to three inches in length-are spread out to the width of the belt-strip and then passed transversely through the body of the beltstrip, at substantially the longitudinal center of the strip and drawn through the same until the filling threads I at the ends of the strip abut against the body thereof as at 7 in Fig. 2, in which the said unraveled ends 5 of the warp threads are shown as passed through the body of the belt-strip in opposite directions at the same point therein.

The belt-layers 2 and 3 are now drawn taut;

jacent portions of the belt-layers 2 and 3 which are then stitched together in the usual manner by parallel lines of longitudinal stltching 8 which, if desired, may be supplemented at the point of splicing by transverse stitching as at 9, though this is not essential. Or the belt-layers might be secured together by an adhesive which may also be used for securing the ends 5 in place, either with or without the stitching 8, the particular means employed, if any, to fasten the ends 5 in place not being of the essence of my invention.

The splice thus: produced is but little thicker than the other portions of the belt, is smooth on both sides, and practically as supple and as strong as any portion of the finished belt.

For the sake of clearness I have shown in the schematic representation of the splice in Fig. 4 of the drawings, the filling threads 4 and warp-threads 6 of the body-portion of the belt-fabric by heavy lines, while the raveled ends of the belt-fabric have their v Figs. 5 and 6 I have shown a belt produced on the same plan but with three belt-layers or convolutions, viz., an outer layer 10, an intermediate layer 11, and an inner layer 12. In splicing the ends of this modified form of belt, the unraveled ends 14 of. the warp-threads 15 the outer end of the beltstrip are passed inward, transversely through the outer belt-layer 10 so as to lie between the same and the intermediate beltlayer 11, while the unraveled ends 16 of the warp-threads at the inner end of the beltstrip are passed outward, transversely through the inner belt-layer 12- so as to lie between the same and the inner face of the intermediate belt-layer 11. The said unraveled warp-ends 1e and 16 are pulled through the belt-strip" until the filling threads at the respective ends thereof abut against the body of the said strip. The beltlayerslO, 11 and 12 are now secured together by stitching, or by an adhesive or in any other approved manner. In this modified construction, the respective unraveled warp-ends let and 16 do not pass through the same portion of the belt-strip as will clearly be seen by-comparing Figs. 4 and 6. On the principle illustrated in Fig. 6, the number of belt-layers may be increased as desired.

I claim 1. As a new article of manufacture, a woven fabric endlessbelt comprising a beltstrip spliced by having its respective ends unraveled to free the ends of its warpthreads. the said warp-thread ends being passed transversely through the body of the strip and drawn through the same, and means for securing the said warp-thread ends in place. i

2. As a new article of manufacture, woven fabric endless belt consisting of a belt-strip wound upon itself to produce a plurality of belt-layers and spliced by having its respective ends unraveled to free the ends of its warp-threads, the said Warpthreatl ends being passed transversely through the body of said strip, and confined in place between the said belt-layers.

3. As a new article of nlanufacture, a woven fabric endless belt consisting of a belt-strip wound upon itself to form a pluralityof belt-layers and spliced by having its respective ends unraveled to free the ends of its warp-threads, the said warpthread ends being passed transversely through the body of the strip and confined in place between the said belt-layers, and means for securing the said belt-layers together.

.4. As a. new article manufacture, a woven fabric endless belt consisting of a belt strip wound upon itself to produce an inner and an outerbelt-layer and spliced by having its respective ends unraveled to free the ends ofits warp-threads, the said warpthread ends being passed transversely in opposite directions through the longitudinal center of the body of the belt-strip and conlined in place between the said belt=layers, and means for securing the said belt-layers together.

5. As a new article of manufacture, a woven fabric endless belt consisting of a belt-strip wound upon itself to form a plurality of belt-layers and spliced by having its respective ends unraveled to free the ends of its warp-threads, the said warp-thread ends being passed transversely through the strip until the ends ofits filling threads are abutted against it, and the said unraveled ends of thewarp-threads being confined between the adjacent lielt-layers, and means for securing the said belt-layers together.

6. As a new article of manufacture, an

endless woven belt consisting of a belt-strip wound upon itself to produce a plurality of belt-layers and spliced by having its respective ends unraveled to free the ends of its warp-threads, the said warp-thread ends being passed transversely through the body of the strip, and lines of longitudinal stitchin securing the said belt-layers together.

A method of making endless woven belts, consisting in windmg a belt-strip uponitself to produce a plurality of overlapping belt-layers the respective ends of the said strip being unraveled to free its warp-threads, then passing the said unraveled ends of the warp-threads of the respective ends of the belt-strip transversely through the body of the same, and finally securing the belt-layers together with the said unraveled warp-ends disposed betweenthem.

8. As an article of manufacture, an end less web belt, comprising a piece of a single ply webbing formed into superimposed layers and having each end provided with projecting warp threads, passing through the adjacent layer and extending lengthwise between adjacent superimposed layers.

As an article of manufacture, an endless web belt, comprising a piece of a single ply webbing formed into superimposed layers and having each end provided with projecting warp threads, passing through the adjacent layer and extending lengthwise between adjacent superimposed layers, and rows of stitches extending in the direction of the length of the webbing and passing through the superimposed layers to umte the same.
